Intro to SwiftUI Data Flow

[@jayxzahn4983]

I really like Jason's way of illustration and explanatoin, which makes confusing SwiftUI concepts easy to understand!

[@alcprado]

I've been into UIKit for 6 years and getting into SwiftUI this year and your video was the mind blowing to me. Now everything makes sense. BTW, I love the way you make videos with old arcades. These take me back to my childhood memories. Double thank you!!!

[@HUNTELAAR11W]

Best explanation of states etc. ever seen on youtube.

[@swiftarcade7632]

Aww thank you Laynay. They certainly confused me. Cheers.

Your channel deserves many more views and attention than it currently has. Kudos to you, for providing such high quality content for free! I wish huge success for your channel.

Been struggling with this for over a week in an app I have been making. This video helped me so much. Thank you!!!!!

I have been learning Swift for a year now, and watched a lot of KZbin videos on this topic. Your explanation is amazing! Thank you !

[@swiftarcade7632]

Thank you for the comment Kamran. Much appreciated. All the best in the New Year!

[@kmaximoff]

@@swiftarcade7632Happy new year for you too! All the best ! :)

Thank you for this nice and easy-to-understand intro guide. Bless you.

[@swiftarcade7632]

You are most welcome. My pleasure.

OMG this is so good. I want to say I still don't fully get why all of these need to exist in SwiftUI but it's already making much more sense to me than previously. They don't make perfect sense yet but they make much better sense now. Thanks!

[@swiftarcade7632]

Most welcome Hongfeng. I had the same question as you when starting out. I myself refer to this video often :) Cheers.

[@MikeG-ol2rj]

Thank you so much for this video, your explanation of the different data flow is really clear.

[@joejarriel]

Clearest walkthrough of this topic at a great pace and depth. Thank you.

[@ValentinaEvdokimova-y3p]

Thank you for this tutorial, it's the best on this topic that I've seen

No words… you are simply great mate… R E S P E C T…

[@silver10188]

Awesome! I'm in the middle of a swiftui app and really needed this. Awesome channel my first video and will be watching more!

[@swiftarcade7632]

You are very welcome Silver. Data flow for me is/was one of the most confusing things about SwiftUI. Glad it helped!

[@mhfs61]

Very educational and helpful. 👍🏼👍🏼👍🏼

Waw🤯❤❤

[@idanboadana3611]

Thank you :) this made a lot of sense to me

[@rasmus4200]

You are most welcome. I found this super confusing at first.

[@swiftarcade7632]

Good to hear Idan. Thx for the comment.

[@magicinternetmoney8715]

Excellent video 🙏🏼. One question: Why must we declare the @ObservedObject throughout the view hierarchy? I thought setting the observed object on the ContentView struct would be enough to trigger a redraw of the contentView's body, and as the body is redrawing, a new DetailView with the newly published Book would be instantiated and so on. So if the redrawing is happening already, why do we need to explicitly pass the @ObservedObject down in the DetailView and DetailHeader?

[@swiftarcade7632]

That's just the way this @ObservedObject works. It needs to be passed to each view that renders it. If you want to avoid that coupling, you can leverage the @EnvironmentObject. That one you can pull out of the air anywhere. Cheers - Jonathan

I see someone likes their Atari 7800 games! Was my first game system and I still have it!

[@swiftarcade7632]

What! Very cool Tim. Asteroid was one of my favorite games. Thanks for dropping by.

[@codeelsewhere]

noice, thanks a lot.

[@swiftarcade7632]

Welcome CodeElsewhere.

[@iOSTechie]

Nostalgia moment when you played the Popeye game video 😍 So far the best explanation I have seen on KZbin on these Property Wrappers. Thank you 🙂

[@swiftarcade7632]

That's awesome Prashant. Not sure who if anyone would remember that game. It was great :) Thx for the comment.
